Abstract This study verified the effects of essential oils from Lippia sidoides (EOLS) and Cymbopogon citratus (EOCC) on the anesthesia of freshwater angelfish (Pterophyllum scalare) of two different sizes (juveniles I (0.82 g) and II (2.40 g)) and on the transport (8 h) of juveniles II. Fish were exposed to different concentrations of EOLS and EOCC: 0, 10, 25, 50, 75, 100, 150, 200, and 250 mg L−1. Ventilatory rate (VR) and transport for 8 h with 0, 10, and 15 mg L−1 of each essential oil were evaluated in juveniles II. The major components found in EOLS and EOCC were carvacrol (44.50%) and a-citral (73.56%), respectively. The best sedation and anesthesia times for both essential oils were obtained with 10 and 25 mg L−1 and 200 and 250 mg L−1 for juveniles I and II, respectively. Fish sedated with EOLS had lower VR values than the other treatments. For transported fish, blood glucose levels were higher in ornamental fish transported with 10 and 15 mg EOLS L−1 and 15 mg EOCC L−1. Hepatic glycogen values were higher in the control group. In general, fish transported with 10 mg EOLS L−1 showed fewer gill histological alterations than other transported fish. When the type of lesion was evaluated, the highest gill alterations occurred in fish transported with EOCC. In conclusion, for the transport of juveniles II, 10 mg EOLS L−1 could be used because although this concentration increased blood glucose, it decreased the VR and caused only mild alterations to the gills.

Abstract: The objective of this work was to assess the fumigant and repellent effects of essential oils on adults of Callosobruchus maculatus and to identify the chemical composition of two of the tested essential oils. For the fumigation test, the oils of Schinus terebinthifolius, Piper aduncum, Syzygium aromaticum, Piper hispidinervum, Cymbopogon citratus, Cinnamomum zeylanicum, and the eugenol compound were tested at different concentrations on C. maculatus adults. For the repellency test, the oils of S. terebinthifolius, P. aduncum, P. hispidinervum, S. aromaticum, Jatropha curcas, and Ricinus communis were evaluated. In the fumigation test, it was observed that P. aduncum and eugenol showed the highest and lowest LC50s, of 169.50 and 0.28 μL L-1 air, respectively. In the repellency test, the oils of S. aromaticum and P. hispidinervum were repellent to C. maculatus. Gas chromatography coupled to mass spectrometry (GC-MS) analysis of these two oils identified 42 compounds, of which safrole was the main component of P. hispidinervum and eugenol of S. aromaticum. The essential oils of S. aromaticum, C. zeylanicum, and the eugenol compound are the most promising to control C. maculatus, via fumigation.

Solvent Extraction Method

This work aimed to extract perfume from the leaves of Cymbopogon citratus using three extraction methods viz: distillation, solvent extraction and expression or effleurage. About 150 g of dried lemons grass were extracted using ethanol as the solvent to obtain essential oils required for the formulation of perfumes. The result of the hydrodistillation process showed that 1.23 g of essential oil per 130g of dry lemongrass produce 0.95% oil at 78 °C, while the effleurage method was 2.55 g of essential oil per 130 g of dry lemongrass sample thereby producing 1.96% oil yield. The solvent extraction method gave 2.7 g of essential oil per 130 g of dry lemongrass sample. This gives about 2.08 % yield of essential oil at a temperature of 78°C i.e. the boiling point of ethanol. The solvent extraction method yielded 2.08%, the effleuragemethod yielded 1.96% and the hydrodistillation method yielded 0.95% essential oil respectively. In conclusion, solvent extraction gave the highest yield because of less exposure to air and heat, which is highly recommended as the most suitable method for the extraction of essential oil.
